JPEG processing - different exposure/brightness than inside CO

I was trying to conduct a quick evaluation of CO and how it handles Fuji cameras. I adjusted, then exported a jpeg using the "high quality" preset baked into CO, but then when I processed it, the resulting image is quite a bit brighter than the preview shown by CO.

It seems that this is an issue that's been brought up before in some ways, but not exactly like this. Using those other posts, I've went on a few wild goose chases, but came up empty every time. I've attached a side-by-side screenshot of my images, from the same monitor so there shouldn't be any color calibration difference or anything. The top image is CO preview, and the bottom is displayed in FastStone. I've also added an image showing my proofing profiles just in case.

I've been using this program for about an hour in total, so I'm very new to it. I'm sure it's something simple that I'm missing. I also realize I need to retake the picture, the face is out of focus, haha.

  So, turning off hardware acceleration, like a post before this one, seemed to have fixed it, The attached pic shows the acceleration on (left) and off (right), the right side image looks just like the Capture One preview, and doesn't have the exposure compromised. I'm posting these findings in case anyone else has trouble with it.

  My PC specs are a Ryzen 3700X, and an Nvidia 2080 w/ the 456.55 driver if this helps out a dev.

  Proof Profile is NOT the same as the Output Profile.

  You can Proof the image using different recipes (profiles), but when outputting it you are using the profile in your output tab.

  Also, in my instance all images looked good before I calibrated my monitor. After calibration, the images looked different when viewed using different software until I included correct ICC Profile in the image.

  Habe auch dieses Problem seit dem letzten Update. Sowohl auf meinem Windows 10 PC als auch auf meinem Mac

  sind die Bilder nach dem Export heller.

  Yeah I suspect the proof profile is the problem too.  I leave mine set to the default ('selected recipe'), and my JPGs and in-C1 edits are identical.  I'm using a very similar setup too, a Ryzen 3800X and 2080 GPU (driver version 452.xx), with acceleration enabled (the speed boost is tremendous).
  
  It does take some time to make sure every part of the workflow is using the same colourspace, some apps just run with whatever the OS has defined, others try to work their own magic and need to be corrected.
